To all whom it may concern Be it known that l, LAWRENCE J. DESEN- BERG, a citizen of the United States, residing at LosAngeles, in the county of Los Angeles ,and State of California, have invented a n front elevation of the upper portion of the machine. Fig. 2 is a horizontal section on line .r2-m2, Fig. 3. Fig. 3 is a vertical section on line cs a, Fig. 4. Fig. 4 is a ver tical section on line what, Fig. 3. Fig. 5 is a verticalsection on line 005-035, Fig. 3, showing one side portion only. Fig. 6 is a perspective of a portion of a coin ejector land slotted arm. Fig. 7 is a perspective of the device as combined with a cash register. Fig. 8 is a section on line S-ws, Fig. 2. Fig. 9 is a side elevation in detail of the movable pinion, its adjusting means, and adjacent portion of its associated gear, showing the. pinion out, of mesh with the gear.

' Fig. 10 is a view similar to Fig. 9 showing theposition of the parts when the pinion is ...engaged with the gear.

.slides in ways C so that the coin tubes with their contents may be lifted out bodily and stored in a safe when desired. At the upper end of each coin tube is a slot 2 to enable j. ing with that denomination,and at its lower Y the tube to be filled with coins correspondend each coinV tube has a discharge slot 3 .through which the coin which is to form the change is to be ejected. A series of slots 4 are arranged in the front of the case and guided 1n the slots 4 are opera-ting ylevers 5 which are pivoted at 6 inside the .case at the rear thereof, and the front end i of .each lever carries a. button 7 on which is,

printed the denomination ofthe ycoinwhich `is controlled by-thatlever.

. Belowthe coin tubes is a'shelf 8 which supports the lowermost coins and also serves .as a guide fora series ofl coin ejectors 9 which are arranged to slide under the respective coin tubes to eject the lowermost coins from the tubes. The rear end of each ejector rod 9 is connected by a connecting rod 12 with a pinion 13, whereby rotation of the pinion 13 will reciprocate the ejector 9 and cause the ejector to push out a coin from the coin tube at each forward move ment lof the ejector. Each pinion 13 is suspended by a bell crank lever 14 pivoted at l5 to a stationary bracket 16, and the other arm of the bell crank lever 14 is arranged underneath an arm 17 which projects down rigidly from the operating lever 5. Arranged at the rear of the respective pinions 13.7are gears 18 all of which are rigidly mounted on a shaft 19 which isprovided with a crank 20. A roller ratchet 2Oa .having its drum 20h secured to the casing 1 prevents rearward rotation of theshaft. Vhenever one of the operating levers 5 is depressed, its arm 17 acts against the bell movements of the ejector' 9 `and will eject one coin at each outward stroke.

The escapement bars 17 are rigidly secured to theoperating levers 5 and project downwardly therefrom, and each consists of a slotted bar asshown. Pivoted to each ejector bar 9 is a pawl Q3 having a roller Q5 a which engages in the concave notches 23h on the escapement bar, and is held yieldingly in engagement therewith by a coil spring 23 and which acts to lift the escapement bar a distance of one notch during each` forward stroke of the ejector bar 9. The escapement bar has a series of notches 23d on its opposite face whichv are engaged by the retaining pawl 23e to yieldingly hold the escapement bar and itsoperating lever 5 in the position set.

When it is desired to make change, the operator will push down one or more of the operating levers 5 according to the denomination of coin desired, moving down the lever or levers a distance in the slots 4 ,to correspond with the number of coins to be ejected...) ForV this purpose each slot 4 is provided with a series of graduations with indieating numerals, as clearly` shown in Fig. 1.

Thus, assuming that the customer has made Vaction in detail.

a purchase amounting-to one cent, and has given in payment a five cent-piece, and four cents is to be returned as change to, the customer, the operator presses down the operating lever 5 to the' indicating numeral 4 at the coin tube f, and inV thus depressing the operating lever 5, it moves down the escapement bar 17 sliding over the ejector bar 9. As the operating pawl 23 and retaining pawl 23e` are both yieldingly held against the escapement bar, they do not prevent its downward movement during the setting operation', as the rounded notches are suiiiciently shallow. During this downward movement of theoperating lever 5, the arm 17 has tilted the bell crank lever 14 and moved the associated pinion 13 into mesh with the corresponding gear 13, and when the bell crank lever 14 has been tilted'downward by the arm 17 sutlicient to place the pinion 13 into mesh with its corresponding gear, the angular position of the bell crank lever is such that its upper end permits the arm 17 to continue its downward movement and hold the bell crank lever and associated pinion in thisposition during such further downward movementof the arm 17., and the bell crank lever and pinion remain in this position Vuntil the arm 17"has again raised suiiiciently to permit Vthe bell crank lever to swing back. Figures 9 and 10 show this The operator then turns the crank 20, which rotates the pinion 13, and as the pinion 13 rotates, it reciprocates the ejector 9 andat each outward stroke ofy vthe ejector a penny is ejected from the coin tube f. During each outward movement of the ejector bar 10, the pawl 23 pushes up the escapement bar 17 a distance of one notch, and as the operating leverhad been moved down four points to eject four pennies, it will v lbe moved completely back by four strokes of the ejector bar, and after having been thus moved back to normal position, the arm 17 will release the bell crank lever 14 and permit the pinion 13 to be moved out of mesh with gear18 by means of spring m so that even though gear may be revolved more than suilicient to eject the four coins, that there will be only four coins ejected,as the revolutions of gear 18 do not actuate the ejecting mechanism after the operating lever 5 has thus been automatically returned to its normal position at the top of its slot 4.

The operation for making change with coins of any other denominationwill readily the ejectors for the coin tubes d and e will be moved out to eject one coin each, a ten cent piece and a five cent piece, and this one stroke w-ill act upon the escapements 17 to restore the operating levers 5 to normal position, so that no more coins will be ejected, and thus fifteen cents in change is provided.

Referring to the last transaction, if it should so happen that the machine should have no ive cent coins in tube e, the operator would have depressed the lever of coin tube d one point for the ten cent piece, and would depress the lever of coin tube f five points to give ive pennies, and then upon turning the crank, the ejector of the tube d would be actuated once, whereupon its operating lever would be restored to normal position, while the ejector of the tube f Wouldbe operated ve times before its operating lever would be returned to normal position, thereby giving change of one ten cent piece and five pennies. A bell 24 is arranged inside the case and is adapted to be struck by an arm 25 which is carried on the gear shaft, the arm being so arranged that it will strike the bell during the initial movement of the shaft.

Vhat I claim is:

1. In a change making machine, a plurality of coin holders, ejectors for the respective coin holders, means for operating said ejectors comprising a gear, a pinion for each ejector, a connecting rod between each pinion and its associated ejector, selecting means for moving the pinion. into mesh with `the gear, and means operating automatically to disconnect the pinion from the gear after the desired number of ejectionshave been performed.
